Magnetism experiment. 17th-century illustration of an experiment being used to measure angles relating to magnetic fields around a sphere. An example of this is magnetic dip, the angle by which a compass needle dips compared to the horizontal. This angle varies with location on the Earth's surface. Artwork from 'Philosophia Magnetica' (1629) by Italian Jesuit physicist Niccolo Cabeo (1586-1650). | |
